Valve Clearance Adjustment
With engine cold, set clearance to 0.012" (.30 mm). To adjust clearance, loosen rocker arm lock nut and adjust screw while measuring clearance with a feeler gauge. Adjust valves in listed order to avoid unnecessary turning of crankshaft. For example, with number eight valve open, adjust valve number one. Rotate crankshaft as required to adjust remaining valves.
